2The estimates for all deposits are presented on a 100% basis.

3The reported estimates of Measured and Indicated Mineral Resources are inclusive of those Mineral Resources modified to estimate Ore Reserves.

4For the Alluvials, cubic metres (m3) have been converted to tonnages using the general bulk density factor of 1.85 t/m3 strictly for the purpose of the summary accumulations. Gold grades have been adjusted from g/m3 to g/t accordingly. Contained gold estimates are not affected.

5Sukhoi Log Mineral Resource estimate is as at 21 February 2017.

6Any minor discrepancies for sums in the table are related to rounding.
